Description
Die Erfindung bezieht sich auf ein Nahrungsaufnahmeventil für eine Atemschutzmaske, durch das hindurch eine Kanüle eines Nabmngsmittelbehälters in das Maskeninnere eingeführt worden kann und das einen Führungskanal für die Kanüle, einen Ventilsitz und einen durch Federkraft gegen den Ventilsitz gedrückten und beim Einführen der Kanüle durch diese vom Ventilsitz entfernbaren, um eine Achse verschwenkbaren Ventilkörper aufweist.The invention relates to a food intake valve for a respirator through which through a cannula of a supply container can be inserted into the interior of the mask and that a guide channel for the cannula, a valve seat and one pressed against the valve seat by spring force and when the cannula is inserted through it, which can be removed from the valve seat and pivoted about an axis Has valve body.
Bei einer bekannten Einrichtung dieser Art ist das Ventil als Klappenventil ausgebildet, dessen Klappe um eine Achse schwenkbar gelagert ist Diese Ausbildung des Ventile bedingt eine genaue Justierung; die kleinsten Verschiebungen der Schwenkachse parallel zur Achse des Föbrungskanals und/oder gering-In a known device of this type, the valve is designed as a flap valve, the flap of which is mounted pivotably about an axis This design of the valve requires precise adjustment; the smallest shifts of the pivot axis parallel to the axis of the Föbrungskanal and / or slightly
δ fttgige Abnutzungen der Dichtungsmittel an der Klappe führen bereits zu Undicbtbehen. δ continuous wear and tear of the sealant on the flap already leads to leakage.
Durch das altere deutsche Patent 2 029 465 ist als Verschlußkörper des Nabrungsaufnabraeventils eine Kugel vorgeschlagen worden, deren Mittelpunkt außer-By the earlier German patent 2 029 465 is as Closure body of the Nabrungsaufnabraeventils a ball has been proposed, the center of which is outside
halb der Längsachse des Fuhnragskanals liegt. Die Kugel wird durch eine Feder, die in einem seitlichen Kanal gelagert und geführt ist gegen den Ventilsitz gedrückt Diese Ausbildung hat den Nachteil eines schräg zum Führungskanal Hegenden Ventilsitzeshalf of the longitudinal axis of the Fuhnragskanals lies. the Ball is held by a spring that is in a lateral Channel mounted and guided is pressed against the valve seat. This training has the disadvantage of a obliquely to the guide channel Hegenden valve seat
*s und bereitet deshalb und wegen der Lagerung der Kugel Schwierigkeiten in der Herstellung.* s and therefore prepares and because of the storage of the Sphere manufacturing difficulties.
Der Erfindung liegt deshalb die Aufgabe zugründe, das Nahrungsaufnahmeventil derart auszubilden, daß die Herstellung einfach, auch mit größeren Fertigungstoleranzen möglich ist und daß sich Abnutzungserscheinungen bei häufigem Gebrauch nicht nachteilig auf die Dichtung auswirken. The invention is therefore based on the task of forming the food intake valve trainees in such a way that the production is simple, even with larger manufacturing tolerances and that wear and tear with frequent use do not have a detrimental effect on the seal.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß, wie bereits vorgeschlagen, als Ventilkörper eine Kugel dient, die mit Spiel in einer parallel zum Ventilsitz verlaufenden Ebene an einem um die Achse verschwenkbaren Rahmen gelagert ist.According to the invention, this object is achieved in that, as already proposed, the valve body a ball is used, with play in a plane running parallel to the valve seat on one to the Axis pivotable frame is mounted.
In der einzigen Figur der Zeichnung ist ein Ausführungsbeispiel gemäß der Erfindung dargestellt.In the single figure of the drawing, an embodiment according to the invention is shown.
Das Ventil besteht aus einem Ventilsitzgehäuse 1 mit einem Ventilsitz 2, einer Schraubkappe 3, einer Kugel 4 in einem Rahmen 5, einem Einführungsschacht 6 und einem diesen überdeckenden SchraubVerschluß 7. Im Einführungsschacht 6 befindet sich ein O-Ring 8, der gewährleistet, daß das System bereits zwischen Einführungskanüle und Einführungsschacht abgedichtet ist, bevor die Kugel durch das Weiterführen der Kanüle geöffnet wird. Die Kugel 4 ist über eine Welle 9 mit Spiel in zwei zueinander senkrechten Richtungen, also in einer Ebene, an dem Rahmen 5 gelagert.The valve consists of a valve seat housing 1 with a valve seat 2, a screw cap 3, a Ball 4 in a frame 5, an insertion shaft 6 and a screw lock covering this 7. In the insertion shaft 6 there is an O-ring 8, which ensures that the system is already between the insertion cannula and the insertion shaft is sealed before the ball passes through the Continuing to open the cannula. The ball 4 is on a shaft 9 with play in two to each other perpendicular directions, that is to say in one plane, mounted on the frame 5.
